Title: Fuel injection control device of internal combustion engine
Inventor: NAKAMURA YOSHITATSU
IPC: F02D43/00
Filed: 2007-02-19
Abstract: <P>PROBLEM TO BE SOLVED: To reduce HC concentration in an exhaust gas while maintaining the stability of combustion when an ignition timing is retarded to the post-top dead center in the compression stroke during cold starting and a fuel is injected at two timings in the compression stroke and the expansion stroke.  <P>SOLUTION: An injection amount in an expansion stroke is larger than that in a compression stroke. The injection in the compression stroke is started after the injection in an expansion stroke of the other cylinder is started, and these injection completion timings are aligned generally with each other. Since the injection in the compression stroke is performed when a fuel pressure is lowered by the injection in the expansion stroke, the penetration of a spray is weakened, the spray is spread and uniform air-fuel mixture is formed, and the adhered amount of a fuel to a cylinder bore is reduced and the HC concentration in the exhaust gas is reduced. At the beginning of the injection in the expansion stroke, the penetration of the spray is increased by a high fuel pressure, and the propagation of fire is promoted by reinforcing a gas flow.  <P>COPYRIGHT: (C)2008,JPO&INPIT
